Rename "CodeReady Containers" to "Red Hat OpenShift Local"

• Red Hat URLs (to double-check, even if redirection works)
• paths found in files (to investigate)
• text lines in .adoc files
• command line tool name changes for described crc commands? (to investigate)
• anything else? (to check)

The following pages and probably some other pages have to be edited upstream:
https://www.eclipse.org/che/docs/che-7/installation-guide/installing-che/
https://www.eclipse.org/che/docs/che-7/installation-guide/installing-che-locally/
https://www.eclipse.org/che/docs/che-7/installation-guide/installing-che-on-codeready-containers/

scoping:

• We can do it now.
• Mentions are only legit in: /installing-che/ /installing-che-locally/ and /installing-che-on-codeready-containers/.
• No mentions of `crc` or `CodeReady Containers` in other docs.
